Abstract: The process for the conversion of heavy crude oils or distillation residues to distillates comprises the following steps: - mixing the heavy crude oil or distillation residue with a suitable hydrogenation catalyst and sending the mixture obtained to a hydrotreating reactor introducing hydrogen or a mixture of hydrogen and H2S; - sending the stream containing the hydrotreating reaction product and the catalyst in slurry phase to a distillation zone where the most volatile fractions are separated; - sending the high-boiling fraction obtained in the distillation step to a deasphaltation step obtaining two streams, one consisting of deasphalted oil (DAO), the other consisting of asphaltenes, catalyst in slurry phase, possibly coke and rich in metals coming from the initial charge; - recycling at least 60%, preferably at least 80% of the stream consisting of asphaltenes, catalyst in slurry phase, optionally coke and rich in metals, to the hydrotreatment zone.

Title: Load tap changer
Inventor: DEGENEFF ROBERT C
IPC: G05F1/16
Filed: 1995-03-29
Granted: 2000-07-18
Abstract: A tap changing system (10') for operation with a transformer (T) and featuring a special group of gate controlled electronic devices (X) that operate as a circuit breaker and recloser such that, after half cycle of short-circuit current, said special group (X) is transferred to the OFF-state, whereby the tap changer (10') winding is open circuited; the advantage being that only the special group of devices (X) need be rated to sustain short-circuit conditions; a further feature is the concept of Discrete-Cycle Modulation (DCM), whereby tap voltage magnitudes are obtainable in increments intermediate the physical tap winding voltage magnitudes.

Abstract: A technique for operating a diode pumped solid state laser in a continuous-wave (cw) mode using diodes blocks (12) that are individually operated in a pulsed mode. For some high power laser applications, it is desirable to provide for operation in pulsed and cw modes, but pump diodes are typically designed for efficient operation in only one of these modes. The invention includes a controller (20) that pulses the individual diode blocks (12) on and off, but not necessarily in unison. For a pulsed mode of operation, the diodes (12) in an array are pulsed either at the same time, or sub-arrays are pulsed in a temporally interleaved manner for a higher effective pulse repetition rate. For the cw mode of operation, the diodes (12) are pulsed sequentially in sub-arrays (A-E), such that at least one sub-array is always energized and the complete array appears to be providing continuous pumping energy. In one embodiment, the sub-arrays (A-E) are columns of the array. In another embodiment, the sub-arrays (12') are each associated with a different solid-state gain medium (10'), the gain media being optically coupled in a single laser.

Title: Water level monitoring float system
Inventor: JAWORSKI ED
IPC: G01F23/76
Filed: 1998-02-11
Granted: 2000-10-03
Abstract: The invention provides an improved float and float system for use in the monitoring of fluid levels, particularly in small diameter wells by way of a cable and float system. The float system includes a number of centralizers which hold the float cable near the center of the well casing and thus reduce the friction of the cable on the casing walls. The addition of weights on the float cable, either or both below the float and between the float and the top of the well casing, can improve the accuracy and operation of the system even further. A truncated cone-shaped float is provided, with a number of fins displaced evenly around the circumference of the float.
